ABSTRACT:
A receiver for a digital transmission system in which transmitted data contain a training data sequence, and the receiver stores a copy of that sequence as it was transmitted. A channel impulse response is estimated based on this stored copy. The received training data sequence is compared with a version of the stored copy that has been modified by the estimated impulse response, and an estimate of the receiving quality is formed based on the degree of match with the modified version.
